EMERGENCY OVERVIEW
Appearance: slightly yellow clear liquid. Flash Point: 65 deg C.
Danger! Poison! May be fatal if inhaled.
Lachrymator (substance which increases the flow of tears).
Combustible liquid and vapor. May cause eye and skin
irritation. Causes digestive and respiratory tract irritation. May
cause central nervous system depression. Moisture sensitive.
Possible sensitizer.
Target Organs: Central nervous system.
Potential Health Effects
Eye:
Causes eye irritation. Lachrymator (substance which increases the
flow of tears). May cause chemical conjunctivitis and corneal
damage.
Skin:
Causes skin irritation. May cause cyanosis of the extremities. May
cause sensitization by skin contact.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea.
May cause headache and dizziness.
Inhalation:
May be fatal if inhaled. Aspiration may lead to pulmonary edema.
Inhalation at high concentrations may cause CNS depression and
asphixiation.
Chronic:
Repeated or prolonged exposure may cause allergic reactions in
sensitive individuals. Prolonged or repeated exposure may cause lung
irritation, chest pain, and pulmonary edema.
Sensitization may be temporary or permanent and results in asthmatic
symptoms in sensitized individuals.
|
Section 4 - First Aid Measures
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid imme
diately. Do NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do not use
mouth-to-mouth resuscitation if victim ingested or inhaled the
substance; induce artificial respiration with the aid of a pocket
mask equipped with a one-way valve or other proper respiratory
medical device.
Notes to Physician:
Treat symptomatically and supportively.
|
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Combustible liquid.
Vapors may be heavier than air. They can spread along the ground and
collect in low or confined areas. Containers may explode when heated.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Do NOT get water
inside containers. In case of fire, use carbon dioxide or dry
chemical.
Flash Point: 65 deg C ( 149.00 deg F)
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 3; Flammability: 2; Instability: 1
|
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Remove all sources of ignition. Absorb spill using an absorbent,
non-combustible material such as earth, sand, or vermiculite. Do not
use combustible materials such as sawdust. Use a spark-proof tool.
Provide ventilation. Do not get water inside containers.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Do not get in
eyes, on skin, or on clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep container
tightly closed. Keep away from heat, sparks and flame. Do not ingest
or inhale. Use and store under nitrogen. Do not allow contact with
water. Discard contaminated shoes. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames. Keep from contact with moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep
refrigerated. (Store below 4癈/39癋.) Store protected from moisture.
|
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
